Could Kentucky be due for more earthquakes? Expert seismologist weighs in
Recently, United States Geological Survey (USGS) data showed a 2.8 magnitude earthquake hit central Kentucky around 3:41 a.m. on Sunday, May 11, originating between Nicholasville and Danville. This tremor comes on the heels of a 4.1 magnitude earthquake that USGS officials pinpointed near the Tennessee-North Carolina border.
According to an interactive earthquake map and database, Kentucky has noticed a roughly 6% increase in seismic activity over the last 30 days.
FOX 56 spoke with University of Kentucky seismologist Seth Carpenter regarding seismic activity in the Bluegrass.

Carpenter said the most recent earthquakes had no connection with the New Madrid seismic zone, despite the tendency of earthquakes to concentrate along the fault line.
Earthquakes are often caused by a sudden slip along a fault, according to the USGS. Carpenter said these slips happen when enough stress builds up to overpower the fault's strength.
Regarding the earthquake on Sunday in Garrard County, Carpenter said it was a rare event, but the magnitude is consistent with past earthquakes recorded there.

The cause of the recent earthquakes is not definitively known, according to Carpenter, since they came from depths of roughly 25-30 kilometers inside the Earth's crust.
He noted that it was difficult to connect the activity at the fault line with future seismic activity.
'It's difficult to say conclusively whether the recent earthquakes foretell of future earthquakes. Nevertheless, it seems unlikely they suggest any increase in likelihood of future earthquakes since none of them has been determined to be part of a sequence,' Carpenter said.
He encouraged anyone concerned about Kentucky earthquakes to download a booklet on earthquake preparedness.

Geological Clues Connect Arizona Meteor Impact To Massive Landslide In Grand Canyon
Aerial view of Meteor Crater in Arizona. getty A new study highlights the striking coincidence in the geologic ages of the famous Meteor Crater in Arizona and a landslide dam that blocked the Colorado River, forming a paleolake in the Grand Canyon 56,000 years ago. Driftwood and lake sediments have been long known in a cave called Stanton's cave in Marble Canyon of eastern Grand Canyon. The mouth of the cave is 45 meter above the river, so how did they end up there? 'It would have required a ten-times bigger flood level than any flood that has happened in the past several thousand years. Or maybe they are very old deposits left as the river carved down, or maybe they floated in from a paleolake caused by a downstream lava dam or landslide dam? We needed to know the age of the cave deposits,' explains Karl Karlstrom, emeritus earth science professor at the University of New Mexico and lead author of the study. In the mid 1960's, Karlstrom's father, Thor, was in the cave as part of a cross-disciplinary geology-archeology research. They found evidence of species that went extinct in Grand Canyon like the California condor and Harrington's Mountain goat; they also found split twig figurines made 3,000 to 4,000 years ago by the ancestors of tribes that live around Grand Canyon. The driftwood was dated to be greater than 35,000 years which was near the limit of the radiocarbon dating method at the time; this age got recalculated in 1984 to 43,500 years. The new study, using new methods and analyses from two labs in New Zealand and Australia reports a date of 56,000 years old. In the 1980's Richard Hereford of the USGS in Flagstaff had proposed that there was a rockslide near Nankoweap Canyon, about 35 kilometers downstream of Stanton's Cave, that might have formed a dam and a paleolake that backed up water and that allowed driftwood to float into Stanton's cave. If so, driftwood should be found also in other caves, flooded at the same time. 'From numerous research trips, Karl and I knew of other high-accessible caves that had both driftwood and sediment that could be dated,' says coauthor Dr. Laurie J. Crossey. The additional wood samples provided ages around 55,600 years. In one — now almost inaccessible — cave there were even beaver tracks preserved in the sand, suggesting that high water levels persisted for quite some time. Based on sedimentation rates in the canyon, the paleolake likely existed for at least 1,000 years before filling up or breaching the landslide dam. Conceptualization of Nankoweap landslide that brought down large boulders of Kaibab Limestone from ... More the cliffs at left and created a geologically short-lived paleolake in Grand Canyon. Karl Karlstrom/University of New Mexico Landslides can be triggered by erosion, earthquakes or volcanic eruptions, but in theory also the shock waves of an asteroid impact could be Coauthor Dr. David Kring, head of the Center for Lunar Science and Exploration, University of Colorado Boulder, and an expert on the famous Meteor Crater in Arizona, had been working to recalculate the age of the crater, concluding that the impact happened 53,000 to 63,000 years ago. Was the Meteor Crater impact enough to cause such a landslide? Kring has written about the physics of this and other impacts and has calculated that the impact would have set off a magnitude 5.4 earthquake (or even M6 using different assumptions) and that the shock wave would still have been ~M3.5 after traveling (in seconds) the 160 kilometers north to Grand Canyon. So, the impact could have 'shaken loose' the steep cliffs of Grand Canyon that were 'waiting and ready to go,' as shown by numerous rock falls that happen in Grand Canyon still today. "The meteorite impact, the massive landslide, the lake deposits, and the driftwood high above river level are all rare and unusual occurrences. The mean of dates from them converge into a narrow window of time at 55,600 ± 1,300 years ago which gives credence to the hypothesis that they were causally related,' concludes Karlstrom. The full study, "Grand Canyon landslide-dam and paleolake triggered by the Meteor Crater impact at 56 ka," was published in the journal Geology and can be found online here.

This Experimental Weight Loss Drug Works Without the Nausea or Vomiting
What if you could lose weight with a drug that won't make you lose your lunch at the same time? New research shows it might be possible. Scientists at the University of Pennsylvania, the University of Kentucky, and other institutions say they've found a potentially novel way to suppress people's appetite and treat obesity—without causing the nausea or vomiting commonly experienced with semaglutide (the active ingredient in Ozempic and Wegovy). In early animal experiments, the team's experimental drug appears to be working as intended. Semaglutide and similar drugs mimic the natural GLP-1 hormone, which is important to regulating our insulin production and hunger. As effective as these medications are at helping people lose weight, they have their tradeoffs—most notably a high chance of gastrointestinal side effects. So there's clearly still a need for improved obesity treatments, according to lead study author Caroline Geisler, an assistant professor at UKY's College of Pharmacy. This Simple Strategy Could Curb One of Semaglutide's Worst Side Effects Geisler and her team have been exploring one particular strategy for treating obesity, involving a protein called octadecaneuropeptide, or ODN. ODN is produced by the brain's glia, specialized cells that support neurons. But glia aren't just the brain's support troops, and ODN seems to be important to controlling our sense of hunger. 'Now we know that [glia] play a large role in sensing and communicating the status of the body, and we hope that by targeting a glial signaling molecule, we can engage many energy-regulating pathways in the brain and avoid the side effects of nausea and vomiting,' Geisler told Gizmodo. The researchers first tested their hypothesis by delivering ODN directly to the hindbrain of rats. Once treated, the rats lost weight and improved their blood sugar control. And when they blocked ODN signaling in rats, the animals exhibited a weaker response to GLP-1 treatment (suggesting its effects are at least partly tied to ODN). Finally, they indirectly dosed mice, rats, and shrews with an experimental drug derived from ODN, called TDN. In mice, TDN improved blood sugar control; in rats, it caused weight loss without nausea or vomiting; and in shrews (animals commonly used to test motion sickness and vomiting), the drug triggered no puking at all. The drug also appeared to not have any noticeable effects on the animals' heart rate, movement, and temperature. 'This paper shows for the first time that giving a smaller version of ODN in the periphery is still effective to improve body weight and metabolic control without side effects,' Geisler said. The team's findings, published Wednesday in Science Translational Medicine, are only a proof of concept for now. There remain many questions about exactly how ODN works in the brain to tamp down our appetite and control blood sugar. It's also possible that ODN-based drugs can be further optimized for medical use, though TDN seemed to produce steady weight loss in animals for at least over a week without waning. Still, the researchers are hopeful this potential new drug class can match or even surpass the effectiveness of today's GLP-1 therapies while being less of a hassle to take. And they're now planning to develop such drugs for testing in people. 'We have an optimistic timeline that we could be ready to start clinical trials within 2 years,' Geisler said. The Best Obesity Drugs Aren't Even Here Yet The study researchers are hardly the only ones working to introduce the next generation of improved obesity and diabetes treatments. But it's likely plenty of people would sign up for a safe weight loss drug that comes without the need for a barf bag.

Worker Sits Down at Their Computer, Horror at What's Inside Monitor
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A Reddit user sparked viral attention after posting a video of ants crawling inside their computer monitor—a surreal and unsettling scene that resonated with thousands online. The clip, featured in a Reddit post titled "Ants inside my monitor," was shared by u/Seapanx in the r/mildlyinfuriating subreddit on July 16 and has since garnered over 17,000 upvotes. The short clip shows multiple ants moving across the interior of the screen, invisible from the outside yet clearly crawling just beneath the monitor's surface. The visual not only is maddening for anyone trying to work, but also presents a unique problem with few cleaning solutions. Beyond the frustration, the invasion has practical implications—and potential long-term damage. Nicole Carpenter, the president of Black Pest Prevention, told Newsweek that, while it may seem bizarre, the phenomenon is not uncommon. "Tiny species like pharaoh ants or crazy ants are actually known to build nests inside electronics," Carpenter said. "Electronics release warmth and offer shelter—your monitor is just a warm safe home for them. Once a few scout ants find it, the rest follow, and they can easily start a colony right inside."

Getty A December 2013 study, published in F1000Research, says: "Temperature influences every aspect of ant biology, especially metabolic rate, growth and development. Maintenance of high inner nest temperature increases the rate of sexual brood development and thereby increases the colony fitness." A May 2021 study in the Annals of the Entomological Society of America also noted that "interest in traits like thermal tolerance that enable ants to survive and thrive in variable climates has increased exponentially over the past few decades 'A Hidden Nest' Carpenter said that, if ants are visible in the screen, it nearly always means a nearby, hidden colony is already established. "In almost every case like this, there's a hidden nest close to the monitor—inside a wall, under furniture, or along a baseboard." Addressing what to do in such a situation, Carpenter advised against using common consumer-grade solutions. "The best solution is to use a professional-grade ant gel bait, such as Advion or anything with a similar active ingredient like indoxacarb," she said. Carpenter added: "In this situation, borax-based baits like Terro aren't the best choice—they work only if the ants are sugar-focused, and they're much slower and less reliable against large colonies." Crucially, Carpenter said you should not try to kill the ants manually: "Never kill the ants you see because they actually help you deliver the poison to the colony. You'll usually see the entire infestation collapse within 10 to 24 hours." A well-intentioned instinct to press on the screen can backfire disastrously, Carpenter added. "Do not press your screen to kill ants. If you crush the ant inside, its body will be stuck there forever and look like a dead pixel," Carpenter said. That warning was echoed by Reddit user u/LoreChano, who wrote in the thread: "DO NOT press your screen with your hands. You will crush them inside and NEVER be able to get the corpse out. It will be like an eternal dead pixel." Others were shocked and sympathetic toward the original poster's dilemma. "This is not mildly but extremely infuriating," wrote Reddit user u/Vegetable_Emotion278. Another commenter, u/shkittel, summed up the general sentiment: "Wow I'm shocked!" User u/Omglizb added: "That's so damn weird! I've never had ants in my actual monitor. But I did wake up a few weeks ago to a bunch of ants on my desk …" Newsweek has contacted the original poster for comment via the Reddit messaging system.
